Protein Tag: N-GST
Uniprot: Q9QZD1
Accession: Q9QZD1
Background: CXCL12, also known as SDF-1, is a CXC chemokine that interacts with CXCR4. SDF-1 alpha and SDF-1 beta are alternatively spliced isoforms of CXCL12. SDF-1 beta has an additional 4 amino acids at the carboxy-terminus.
Bio Acitivity: Not validated for activity
Sequence: Gly 21-Lys 89
Purity: > 95% as determined by reducing SDS-PAGE.
Formulation: Lyophilized from sterile PBS, pH 7.4.
Normally 5%-8% trehalose, mannitol and 0.01% Tween 80 are added as protectants before lyophilization.
Please refer to the specific buffer information in the printed manual.
Reconstitution: It is recommended that sterile water be added to the vial to prepare a stock solution of 0.5 mg/mL. Concentration is measured by UV-Vis.
Endotoxin: < 10 EU/mg of the protein as determined by the LAL method.
Calculated MW: 32.5 kDa
Observed MW: 35 kDa
